I couldn't find a answer so i hope some people in this situation could chime in.

my 3 road bikes are in campy and i accumulated some wheels but recently i was considering getting sram etap for my next bike.

Would I be able to switch any wheels regardless what cassette is on, of course with proper adjustement?According to this article it shouldn't be a problem, but i am not totally convinced since it isn't exactly the same spacing between cogs: http://fitwerx.com/campagnolo-shimano-a ... patiblity/

If i understand well how etap is set, you could micro-adjust at every cog to have a perfect shift, at least noiseless. That should mean i could swap any wheelset without any concern.

For etap users who have tried switching between campy/shimano/sram cassettes, is it working well? is there anything that i missed?

Ever since Shimano followed Campy's lead into 11-speed many years ago (6 or 7?), this question has been coming up. As a reader of all the pieces that have been written, I can say that as a Campy user myself, I would have no hesitation in fitting eTap to a Campy setup. Perhaps there is a reader here who has personal experience.

Your link simply confirmed what has been researched many times

So, we started swapping wheels between three bikes 11 speed bikes (one SRAM, one Shimano and one Campagnolo) on the workstand. It presented no problems whatsoever; you could get a decent shift with any 11 speed wheel on any 11 speed bike in the stand. However, what works on the workstand may not work so well under actual riding conditions, when torque and weight are applied. So, outside I went with these combinations. Except for the usual niggling problems that occur when swapping one brand of wheel for another, requiring derailleur adjustments to account for cassette placement, the various combinations worked fine.

There's sometimes a buggy.How many drivers does a buggy have?

One.

So let's just say I'm drivin' this buggy...and if you fix your attitude you can ride along with me.

They're not. Going this way or another ( Campa on Shimano/Sram cassette or reverse ) you'll notice more noice from chain&cassette on certain cogs, and shifting performance decrease as well. Adjust to your preference where it will be but it will. Difference between spacing and cassette width is tiny, but noticeable. It's simply not this "working culture" as homogenic Campagnolo or Shimano. Sram users will be most happy : American cassettes never been known as "silent" nor "smooth& fast shifting".

Small disclaimer : I'm used to different levels of "perfect". Most of them I wouldn't describe even as "satisfactory"... so take a margin for it. Bigger- better

From strictly functional point of view it is possible to achieve very very good shifting performance between two systems : it require perfect RD hanger alignment and bit more time for indexing adjustment, best tested on route, not stand. Chain will also make a difference. IMO chain should "suit" cassette ( so Campa cassette-> Campa chain ).

I had to micro adjust my setup to get a Campagnolo equipped wheel dialed in on my etap setup. Doesn't take much, but a click or two an any one of the positions that doesn't shift fast enough is all that's needed.

It's fine. You'll not be able to tell the difference. I swap Campag (Record and Chorus cassettes) wheels onto my S3 with eTap and my R5Ca with Di2, and Shimano/SRAM (mostly XG1190, but also PG1170 and Ultegra) onto my Excel with 2015 SR. I honestly can't always remember which combination I'm running.

I've had a travel bike (Moots with S&S couplings for several years). After having my LBS install new cables last year, I found it really hard to reconnect the cables. So when the bike came home from last winter's sojourn in Maui, I had my LBS install etap shifters, derailleurs and brakes. Stuck with my White 46/30 crank and Campy Record hubs and 11-32 cassette. The bike has been ridden about 1,000 km so far with that set up with no problems. And it sure is easier to put the bike together after removing it from its case.

After over 20 years on Campy with a couple of diversions to Di2, I think I'd only buy etap for new bikes. It just works really well.
